F.BROCKMULLER APPARATUS FOR CONTINUOUSLY WINDING WEBS OF PAPER 5Sheets-Shem 5 Filed Aug INVENIOR griedrich F'rclnz BROCKMULLER g wcm aHal ATTOR NEYS United States Patent Int. Cl. B65h 35/04 US. Cl. 242-56Claims ABSTRACT OF THE DISCLOSURE Apparatus for winding webs of paperincludes a first guide means which holds a spindle assembly after a webof paper being wound about it reaches a certain size, and a second guidemeans which holds the spindle assembly before the roll'forrned by theweb reaches that size and delivers it to the second guide means.Consequently a continuous web may be successively rolled onto thespindles of successive spindles assemblies.

The invention relates to an apparatus for continuously winding a web ofpaper or the like delivered by a processing machine, for example aprinting machine.

Apparatus is known in which the web to be wound is guided between twocarrying rollers which drive the wound roll and such apparatus has theadvantage of very quiet winding, since the wound roll is automaticallypressed against the carrying rollers. Moreover, an extremely tight andfirm winding can be performed. However, it is a disadvantage that insuch apparatus the Wound roll cannot be removed and replaced duringcontinued operation of the apparatus.

It is an object of the invention to provide an apparatus in which thewound roll can be removed and replaced during continued operation of theapparatus, even with arrangements in which the web is guided between thecarrying rollers, and the wound roll bears to a large eX- tentsimultaneously against both carrying rollers.

To this end, according to the invention one of the carrying rollersco-operates in known manner with a spindle transferring device and ismounted with provision for horizontal displacement, and when thecarrying roller is withdrawn, a driven auxiliary roller can beintroduced between the two carrying rollers, the web -being guidedbetween the auxiliary roller and the displaceable carrying roller. Theresult is that during the winding operation the wound roll runs quietly,and when the wound roll is to be removed and replaced, the processingmachine up stream need not be stopped, so that production is increased.The spindle transferring device can take the form of a pair of forks ordisplaceable guide in known manner, as disclosed in German patentspecification No. 1,137,916 in dependence on the loads occurring.

Preferably, the auxiliary roller is in driving connection with thestationary carrying roller.

An embodiment of the apparatus according to the invention will now bedescribed with reference to the drawings, in which FIGS. 1 to 3 arediagrammatic side elevations of the apparatus in three different workingphases.

A web 1 of paper or the like, arriving from a processing machine, forexample a printing machine, is guided over deflecting rollers 2-4 to afeed device 5, 6, whose roller 5 is regulatably driven from theprocessing machine. The web 1 runs over a deflecting roller 7 and thenover an auxiliary roller 8 at some distance from the roller 7 (see 'FIG.1). At a fixed carrying roller 9, which is driven by any suitable motoror drive mechanism the web 1 finally runs on to the roll 10 on which theWeb is wound. The wound roll 10 is mounted on a spindle 11 retained inbearings 12, .13 supported on both sides by rollers 14, 15 which run invertical guides 16, 17 in the form of channels in the machine frames 18,19 on both sides. As the diameter of the roll 10 increases, the bearings12, 13 move progressively higher in the guides 16, 17. When the requireddiameter has been reached, the wound roll 10 can then be lifted outtogether with the spindle 11.

In the working phase illustrated in FIG. 1 the auxiliary roller 8 hasbeen pivoted into a stand-by position. The auxiliary roller 8 is mountedon a pair of rocking levers 20, 21 which can pivot around the shaft v22of the carrying roller 9. The auxiliary roller 8 and the carrying roller9 are kinetically interconnected by a driving chain 23. A parting blade24 can be moved by means of a pair of levers 25, 26 around the pivot 27of the auxiliary roller -8. Lateral members 29, 30 are guided fordisplacement in the horizontal direction in FIGS. 1 to 3 on both sideson a base block 28. The lateral members 29, 30 are shown in FIG. 1withdrawn from the working zone. The lateral members 29, 30 bear asecond carrying roller 31 which is driven by a motor or any suitabledrive mechanism and guide blocks 32, 33 for spindle bearings 34, 35which are supported with provision for vertical displacement by rollers38, 39 running in guides 36, 37. Discs 40, 41 are driven from thecarrying roller 31 via V-belts 44, 45 tensioned by means of tensioningdiscs 42, 43. The discs 40, 41 bear against the spindle 46 which bears asleeve 47, and bring the latter to a peripheral speed corresponding tothe speed of the web. In the prepared working position, the spindle 46is located in its position by stops 48, 49 disposed on the lateralmembers 29, 30 and by stops 50, 51 disposed on the guide blocks 32, 33.The discs 40, 41 and the tensioning discs 42, 43 are mounted in bearingmembers 54, 55 which can be pivoted around the pivot 52 of the carryingroller 31 by means of a hydraulic adjusting member 53.

FIG. 2 shows that phase of operation in which the wound roll 10 has justreached the required diameter and the Web 1 has been parted by theparting blade 24. At the moment of parting of the web 1, the hydraulicadjusting member 53 pivots back the V-belt drive with the V-belts 44, 45the tensioning discs 42, 43 and the drive discs 40, 41 for the spindle46. The abutment for the spindle 46 and the bearings 34, 35 is thereforeremoved, so that the latter drop in the guides 36, 37 together with thespindle 46 on to the auxiliary roller 8, which has in the meantime beenbrought into the correct position. Since the sleeve 47 disposed on thespindle 46 is wound around with a strip which sticks on both sides, andits peripheral speed corresponds to the web speed, the fresh end of theweb immediately sticks to the sleeve 46 and is wound. The drive of thesleeve 47 on which the fresh wound roll 56 as shown in FIG. 3 is formed,is now performed by rolling down over the driven auxiliary roller 8, asshown in FIG. 2. In the meantime the wound roll 10 can be removed fromthe apparatus. When the wound roll 56 has reached a certain size, thedisplaceable carrying roller 31 takes over the drive of the wound roll56, and the auxiliary roller "8 is pivoted out of the plane of thecarrying rollers 9, 31, so that the lateral members 29, 30, the carryingroller, and the guide blocks 32, 33 together with the wound roll 56retained in the bearings 34, 35 can be displaced in the direction of themachine frames 18, 19 on both sides and the carrying roller 9.

In the phase illustrated in FIG. 3, the displacement of the lateralmembers 29, 30 has reached its final position, in which the guide blocks32, 33 fit into corresponding recesses in the machine frames 18, 19. Theguides 16, 17 form a vertical continuation of the guides 36, 37 and thebearings '34, 35of the spindle 46 move, as a result of the increasingdiameter of the wound roll 56, upwardly out of guides 36, 37 and intoguides 16, 17.

In the final phase of the winding operation of the wound roll 56, thelateral members 29, 30 are driven back into their starting positions, sothat the bearings 12, 13 released with the removal of the Wound roll canagain be introduced into guide members 32, 33, to receive the releasedspindle 11 with a newly slipped-on sleeve, thus preparing the wholeapparatus for the next change of roll.
